### Data
Data were measured in multiple times per subject, once at the start of the season, once at the end of the season and everytime the subject had a concussion.
the data is labeled alphabetically from starting from a to represent the EED data collection for different times.
if a subject has data labeled as:
* a : measurement beginning of the season
* b : measurement after the first concussion
* c : measurement after the second concussion
* d : measurement the end of the season
Note Some subject may not had any concussions, or may have missing data where they did not show up at the beginning of the season.
